Characteristics of recirculating ball steering gear
·It can achieve the characteristics of gear ratio and meet the requirements of portability. The intermediate position has a small steering force and is frequently used, requiring sensitive steering. Therefore, it is hoped that the speed ratio near the intermediate position is small to improve sensitivity. The large angle steering position has high steering resistance, but it is used less frequently. Therefore, it is hoped that the speed ratio at the large angle position will be larger to reduce the steering force. Due to the fact that recirculating ball steering gear can achieve gear ratios, its application is becoming increasingly widespread.

What is the classification of hydraulic Power Steering Pump?

1. From the perspective of vehicle types, hydraulic power Steering Pump can be divided into commercial vehicle pump and passenger vehicle pump.

2. From the perspective of structural forms, hydraulic power steering pump can be divided into vane pump, Gear Pump and plunger pump. Among them, vane pump is widely used in various vehicle types due to its advantages of small size, low noise, and high volumetric efficiency.

3. From the perspective of driving forms, hydraulic power steering pump can be divided into gear driven steering pump, belt driven steering pump, and crosshead key (spline) steering pump. Among them, belt driven steering pump is mainly used to drive passenger cars with smaller torque, while gear driven and crosshead key steering pumps are more common in commercial vehicles.
